he is a ki user??? y'see i though he is a magical beastman thingy. that's why rakan said "taking out magical beast is my sepciality as a mercenary" when he take out kotarou. and what about secchan, she's a ki user yet she can still do eastern style magic 'lan'

I don't think that's possible. One of the two must be a mage, and kotarou is a Ki user.

Kotarou's ninja ability and martial arts may be powered by Ki, but what about his inugami-using?
That is definitely not a martial art, so it is unlikely it is powered by Ki. So it is ether magical in nature (thus allowing Kotarou to have a partner) , or it is some new clerical magic that works by some contract with those inugami. Knowing Kotarou, the clerical option is unlikely.

well, I think that is the ability to control spirits. If i am not mistaken those are summoned spirits.

But what i wanted to say was that kotarou isn't a mage. Until now only mages are able to make a pactio. That said, there's no impossible thing in a manga like Negima...

The suprise part of this chapter as well as in the Ch. 250 raw was Yue and her group running into Negi, Chisame, and Nodoka. Nodoka should have been a little more careful after seeing Yue. I don't want Negi to be capture unless it is a part of a plan to decieve Fate, his team, and his allies.

At least, Negi is sending a recon team to the Old Ostia gateport. To fool Fate and his team, all Negi has to do is to be part of a group of tourists. Yet, Negi doesn't suspect the false Asuna.
